Here I think they are not talking about the money, actually, they are talking about the risk involved in it, the heartbeat when you place a bet, the nervousness when you are not fixed on one, and the feeling of that moment when you are lossing money can give more pleasures. This is a mentality that is beyond understanding because everyone is coming to earn from here or enjoy the game, but some are born different, they get their enjoyment when they are losing money. They don't play the free games because there is no thrill in it, as all the things are free for casuals.
